Self-adhesive composition for the bonding of substrates with low surface energy
A hot-melt adhesive composition comprises a mixture of silylated polymers, a tackifying resin and a catalyst, in specific contents, having self-adhesive properties after crosslinking to moisture. A self-adhesive article comprises a support layer and at least one self-adhesive layer obtained after crosslinking to the moisture in the adhesive composition according to the invention. The self-adhesive article can be used to bond low-energy substrates, in particular plastic substrates, notably thermoplastic substrates having low surface energy.

Oxidic silicon particle dispersion in polyol
A graft macromer, comprising the reaction product of at least one macromer being at least one molecule which comprises in its structure one or more hydroxyl-terminated polyether and/or polyester chains, with at least one grafting compound which comprises in its structure at least one at least monoalkoxylated or at least monohalogenated silyl group and at least one alkyl, cycloalkyl or aryl containing group which is reactive towards the hydroxyl group of the macromer, is used for dispersing e.g. SiO.sub.2 in a polyol.
CONDENSATION CURABLE COMPOSITION
A moisture-curable composition is shown and described herein. The moisture-curable composition comprises a moisture-curable resin and a moisture scavenger selected from a cyanoalkylalkoxysilane. The inclusion of the cyanoalkylalkoxysilane in the moisture-curable composition has been found to effectively scavenge moisture and control the rate of curing and viscosity increase in the composition.
